aarch64: Add -march support for Armv9.1-A, Armv9.2-A, Armv9.3-A
This is a straightforward patch that allows targeting the architecture revisions mentioned in the subject
through -march. These are already supported in binutils.
Bootstrapped and tested on aarch64-none-linux-gnu.
gcc/ChangeLog:
* config/aarch64/aarch64-arches.def (armv9.1-a): Define.
(armv9.2-a): Likewise.
(armv9.3-a): Likewise.
* config/aarch64/aarch64.h (AARCH64_FL_V9_1): Likewise.
(AARCH64_FL_V9_2): Likewise.
(AARCH64_FL_V9_3): Likewise.
(AARCH64_FL_FOR_ARCH9_1): Likewise.
(AARCH64_FL_FOR_ARCH9_2): Likewise.
(AARCH64_FL_FOR_ARCH9_3): Likewise.
(AARCH64_ISA_V9_1): Likewise.
(AARCH64_ISA_V9_2): Likewise.
(AARCH64_ISA_V9_3): Likewise.
* doc/invoke.texi (AArch64 Options): Document armv9.1-a, armv9.2-a,
armv9.3-a values to -march.
